fication.

This invention relates to means for affording a visible indication of the flow of the lubricating or other fluid from a force-feed pumping apparatus, and more especially a pumping apparatus of the multiple-discharge type; and the present improvement has for its object to provide a simple and efficient structural formation and combination of parts by means of which temporary visible indications of the flew of fluid can be obtained when so desired and with which a positive pulsating feed is had at the point or points of delivery when such temporary visible feed is in its inactive or dormant condition, all as will hereinafter more fully appear and be more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation, partly in section at line Fig. 3, of a cluster of six individual sightfeeds embodying the present invention. Fig. 2 is a plan view of the same. Fig. 3 is a ltransverse section of the same at line x',

Fig. 1. Fig. 4 is a detail transverse section at line a02 :122, Fig. 6. Fig. 5 is a plan view of the body portion or trunk, partly in section at line ac3 x3, Fig, 3. Fig. 6 is a front elevation of the same, partly in section at line x Fig. 3.

Similarl numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 is the body portion or trunk of the present appliance, which in the multiple and preferred form of the present invention is formed with two series of passages 2 and 3 in vertical alinement, a series of horizontal passages 4, a longitudinal orifice or chamber 5, arranged at the intersection of the passages 4 with the passages 2 and 3 and common to the entire series of vertical and horizontal passages, and a series of companion passages 6 in its upper portionl in adjacent relation to the uppermost series of vertical passages 2, with both series of said passages 2 and 6 opening through the top of the trunk, as shown.

7' represents a series of annular recesses in the top of the trunk, forming a series of receiving-chambers for the lower ends of the series of transparent sight-tubes S, which are secured therein in any suitable and well-known manner. Each annular recess and its sighttube is individual to an individual pair of passages 2 and 6, and said passages communicate with the interior of said sight-tube to constitute inlet and outlet passages therefor, as hereinafter more 'fully set forth.

9 represents cap-pieces secured to the upper ends of the sight-tubes in any usual and well'- known manner to constitute closures for the upper ends of said sight-tubes.

10 represents a series of vertical dischargenozzles located within the sight-tubes and having connection at their lower ends with the series of vertical passages 2 and adapted to discharge the fluid from saidpassages into the upper ends of the sight-tubes and so that the fluid will flow down the sight-tubes in a visible manner.

11 is a secondary longitudinal passage formed in the body or trunk 1, and communieating in common with the series of companion or return passages 6 aforesaid.

12 is a pipe adapted to connect the longitudinal passage 11 with the supply-tank of a multiple discharge pumping apparatus to which the present invention is applied and through which the fluid from the series of sight-tubes is adapted to return by gravity into said supply-tank in the normal use of the apparatus.

13 represents a series of pipes adaptedto connect the series of horizontal passages 4 in an individual manner with the outlet or discharge passages of a multiple-discharge pumping apparatus.

14 represents a series of pipes adapted te connect the series of vertical passages 3 in an individual manner with the different points at which a discharge of the fluid is required as, for instance, the various bearings of an engine, an automobile, or the like.

15 is a cylindrical valve-head fittingthe aforesaid longitudinal orifice or chamber 5 of the trunk and provided with a series of angular ports 16, individual to each chamber of passages 2, 3, and 4, as shown more particularly in Figs. 1 and 3. The arrangement is such that a quarter-turn of said valve-head in one direction will cause the angular ports 16 to register the passages 4 with the lower vertical points of use and by a quarter-turn .in

IOO

the other direction will cause said angle-ports 16 to register the passages 4 with the upper vertical passages 2 to cause the fluid to discharge into the sight-'tubes and afford a visible indication of workings of each one of the multiple discharges of the pumping apparatus. Such visible indications are had at the will of the operator in ascertaining the condition of the feed to the Various points at which the fluid is used. Normally, however, the parts will be in the condition first described, with no discharge into the sight-tubes and with the multiple discharge from the pumping apparatus moving in a positive and pulsating manner to the different points of use.

17 is a handled stem projection at one end of the valve-head 15 for convenient operation of the same.

18 represents flat faces formed in a part of the circumference of the valve-head 15 at right angles to each other and adapted for engagement by a spring follower-plug 19, moving in the trunk 1, to insure the proper register of the ports in said valve-head with the passages in said trunk in either position of the valve-head.

20 and 21 are screw-plugs or bushings fitting the respective ends of the passage or chamber 5 and adapted to hold the valvehead 15 in place in said passage or chamber.

22 is a spring interposed between the bushing 21 and the end of the valve-head for yieldingly holding said valve-head to its end bearing against the bushing 20 aforesaid.

23 is a plate or bracket upon which the present appliance is supported and which when circumstances so indicate may be a vertical wall of the casing ofthe pumping apparatus.

24 is a sheet-metal angle-plate secured to the bracket 23, with its upper and horizontal flange provided with a series of orifices for the reception of the upper ends of the sighttubes to retain the same in proper vertical position against accidental displacement in continued use.

25 is a sheet-metal angle-plate secured to the front of the trunk 1, with its upper and horizontal flange provided with a series of orifices fitting the base of the sight-tubes and adapted to cover over the upper and front surfaces of the trunk and afford a plain, economical, and easily-cleaned finish for that portion of the apparatus.
